20110017353 | METHOD FOR MAKING A REFRACTORY CARBIDE LAYER ON A PART MADE OF C/C COMPOSITE MATERIAL - The invention relates to a method of making a refractory carbide layer on the accessible surface of a C/C composite material, the method including a step consisting in placing the composite material in contact with a reactive composition in solid form that contains an atomic proportion greater than or equal to one-third and less than or equal to 95% of a metal that is a precursor of a determined carbide having a melting temperature greater than 2000° C., and an atomic proportion of silicon that is greater than or equal to 5% and less than or equal to two-thirds. The method further includes a step consisting in impregnating the accessible surface of the C/C composite material with the reactive composition melted at a temperature that is greater than or equal to the melting temperature of the metal that is a precursor of a determined carbide. | 01-27-2011 |

20110093223 | BATTERY STATE-OF-CHARGE MANAGEMENT METHOD - Equipment and methods for estimating and regulating the state of charge (SOC) of a battery in a hybrid fuel cell-battery system for use in a moving vehicle. The SOC is continuously estimated and the fuel cell power is regulated to maintain the SOC at a level such that the battery has enough stored energy to operate motors used in the vehicle, and enough spare capacity to accept regenerative energy from these motors during further operations. | 04-21-2011 |
20150024298 | SYSTEM AND METHOD FOR TUNING AN ELECTROCHEMICAL CELL STACK - The present disclosure is directed to a method for tuning the performance of at least one electrochemical cell of an electrochemical cell stack. The method includes supplying power to an electrochemical cell stack. The electrochemical cell stack includes a plurality of electrochemical cells. The method further includes monitoring a parameter of at least one electrochemical cell and determining if an electrochemical cell becomes impaired. The method also includes diverting a fraction of the current flow from the impaired electrochemical cell during operation of the electrochemical cell stack. | 01-22-2015 |

20140324370 | Battery State-of-Charge Aggregation Method - Embodiments of the disclosure may include a method of managing a state of charge of a battery having a plurality of battery cells. The method may include calculating an individual state of charge for each battery cell, calculating an average state of charge for the battery cells, defining a minimum and a maximum average state of charge threshold, and calculating an overall state of charge for the battery such that when the average state of charge is below the minimum threshold, the overall state of charge is calculated based on the state of charge of a subset of battery cells having the lowest state of charge, and when the average state of charge is above the maximum threshold, the overall state of charge is calculated based on the state of charge of a subset of battery cells having the highest state of charge. | 10-30-2014 |

20090198408 | Method and Apparatus for Diagnosis of Sensors Faults Using Adaptive Fuzzy Logic - A method for monitoring the sensors in a vehicle control system. The method includes identifying a plurality of potential faults, identifying a plurality of measured values, and identifying a plurality of estimated values based on models in the control system. The method further includes identifying a plurality of residual error values as the difference between the estimated values and the measured values. The method also defines a plurality of fuzzy logic membership functions for each residual error value. The fuzzy logic membership functions are adaptive in that they change depending on the vehicle operating region, i.e., the non-linearity level of the vehicle, and the vehicle operating conditions, i.e., steady state verses transients. A degree of membership value is determined for each residual error value based on the membership functions. The degree of membership values are then analyzed in a fuzzy logic reasoning system to determine whether a potential fault exists. | 08-06-2009 |
